Description

The present invention relates to a contact set for connecting a multi pair communication cable having wire pairs, in particular individually shielded wire pairs, said set comprising a male connector provided to be plugged into a female connector, said female connector comprising a first, a second, a third and a fourth pair of connection pins provided for being connected to corresponding wires of said wire pairs.
Such a contact set is known from EP 0 755 100, wherein said four pairs of pins are each provided in a separate holder part. By the provision of separate holder parts, crosstalk between the different pairs of connection pins is considerable reduced providing in such a manner a good transmission characteristics up to and possibly beyond 600 MHz.
A drawback of this known contact set is that the female connector presents a specific configuration so that only a male connector having a corresponding specific configuration may be mated in the female connector. In particular, a known RJ-45 male connector may not be mated therein.
The object of the present invention is to provide a contact set which allows transmission with high frequencies, in particular up to and possibly beyond 600 MHz, but wherein the female connector is still compatible for plugging in known RJ-45 male connectors with frequencies up to 100 and 200 MHz ( category 5 or 6 connectors).
To this object the contact set according to the invention is characterised in that said female connector comprises a central pair and a further pair of pins in such a manner to form an aligned series of pins with said third and fourth pairs of pins wherein said central pair is located in the middle of said series and the two pins of said further pair of pins are located on both sides of said central pair of pins, said third and fourth pairs of pins being each located at a respective extremity of said series, said central pair of pins being connected to a first pair of electrical contacts connecting the central pair of pins with said first pair of pins and said further pair of pins being connected to a second pair of electrical contacts connecting the further pair of pins with said second pair of pins in such a manner that upon connection of a first male connector having corresponding first and second pairs of pins provided in first and second holder parts separate from the other pins, said first and second pairs of electrical contacts are released, and upon connection of a second male connector consisting of four aligned pairs of pins mating in said series of pins, said first and second pairs of electrical contacts are held.
The formed configuration of eight aligned pins comprising the third and fourth pairs of pins and the additional pairs of pins, i.e. the central and further pairs of pins, corresponds to a configuration of an RJ-45 connector so that the obtained female connector is compatible for plugging in known RJ-45 connectors. By the provision of the electrical contacts between the central and first pairs of pins, on the one hand, and the further and second pairs of pins, on the other hand, the electrical signals when using an RJ-45 connector are transmitted from the central and further pairs of pins via the first and second pairs of pins to the wire pairs connected to the first and second pairs of pins. When plugging in a male connector having corresponding first and second pairs of pins, the electrical contacts are released so that electrical signals will be transmitted from the first, second, third and fourth pairs of pins from the male connector to the first, second, third and fourth pairs of pins from the female connector. This transmission may be achieved with high frequencies since the first and second pairs of pins of the male connector are located in separate holder parts, since the remaining third and fourth pairs of pins are sufficiently spaced apart from each other, i.e. at both extremities of the aligned series and since the central and further pairs of pins do not receive electrical signals, the electrical contacts with the first and second pairs of pins being released. Thus, the electrical signals do not reach the central and further pairs of the female connector. This results in an absence of crosstalk between those pins.
In order to further reduce interference, each pair of pins in said first male connector is provided in a corresponding holder part, each holder part being separated from one another by means of a shield. Preferably, said shield is provided for grounding said further pair of pins of the female connector upon connection of said first male connector.
Preferably, said male connector comprises a corresponding central pair of connection pins provided to be mated into the central pair of pins in the female connector. This enables to use the central pairs of pins for additional electrical signals.
The invention also relates to a female connector to be used in a contact set according to the invention.
The invention will now be described further in detail referring to the annexed drawings, wherein:
  • Figure 1 is a perspective view illustrating the front part of a female connector according to the invention;
  • Figure 2 is a perspective view illustrating the back part of the female connector according to Figure 1;
  • Figures 3 and 4 illustrate a side and a front view of a male connector according to a first preferred embodiment of the invention;
  • Figures 5 and 6 illustrate a side and a front view of the female connector according to Figure 1;
  • Figures 7 and 8 illustrate an RJ-45 male connector;
  • Figure 9 is a perspective view of a male connector according to a second preferred embodiment of the invention;
  • Figure 10 is a front view of the male connector according to Figure 9;
  • Figure 11 is a side view of the male connector according to Figure 9;
  • Figure 12 is a back view of the male connector according to Figure 9;
  • Figure 13 is a top view of the male connector according to Figure 9;
  • Figure 14 is a side sectional view of the female connector taken along line XIV-XIV from Figure 15;
  • Figure 15 is a side view of a female connector according to a second embodiment provided for receiving the male connector according to Figures 9 to 13;
  • Figure 16 is a top view of the female connector taken along line XVI-XVI from Figure 14; and
  • Figure 17 is a back view of the female connector according to Figure 14.
    • Referring to Figures 1 and 2, there is illustrated a female connector according to the invention. This connector comprises a first pair of connection pins 1 located in a first holder part 7 and a second pair of connection pins 2 located in a second holder part 8. A further holder part 9, is designed for receiving an RJ-45 male connector as will be described further. This further holder part comprises a series of connection pins 3 to 6, comprising at a first extremity of the series a third pair of connection pins 3 and at the other extremity a fourth pair of connection pins 4. As illustrated in Figure 2, a series of eight wires 10-17 are provided for being connected to the connection pins 1 to 4 respectively. The pairs of wires are separated from one another in order to reduce crosstalk at their connection with the connection pins. Preferably, each pair of wires is shielded, as illustrated in Figure 2.
    According to the invention, there are provided a central pair 5 and a further pair 6 of connection pins, so as to mate with the corresponding pins provided in a standard RJ-45 male connector, as will be described further when referring to Figures 7 and 8.
    Figure 5 illustrates that the further pair 6 of connection pins from the female connector is electrically connected to the second pair 2 of connection pins, by means of electrical connections 18. Similarly the central pair 5 of connection pins is electrically connected to the first pair 1 of connection pins (not shown). When plugging in a male connector having corresponding holder parts 7' and 8' (Figures 3 and 4) with corresponding first 1' and second 2' pairs of connection pins, the electrical connections 18 are released, so that signals transmitted through wires 14' to 17' will be transmitted to the wires 14 to 17 through the intermediary of pins 1'-1 and 2'-2 and will not pass through the pins 5 and 6. Signals transmitted through wires 10' to 13' will be transmitted to the wires 10 to 13 through the intermediary of pins 4'-4 and 3'-3. Since those pins 4'-4 and 3'-3 are located at the extremities of the series of pins, as clearly illustrated in Figures 4 and 6, crosstalk between those pairs of pins is rather limited, even with high transmission frequencies up to 600 MHz.
    Preferably the holder part 8' from the male connector comprises a shield 19 (Figures 3-4) in such a manner that upon plugging in this connector in the female connector (Figures 5-6), the further pair 6 of pins may be grounded since the released electrical connection 18 comes into contact with the shield 19.
    Additionally, the holder part 7' could for the same reason also be shielded so as to ground the central pair 5 of pins. According to an alternative, the central pair is not grounded but used for an additional signal. For this purpose, the male connector comprises a corresponding central pair 5' of pins. Possibly the male connector may also comprise a further pair 6' of pins. In the male connector, the first 1' and second 2' pairs of pins are not connected to the central 5' and further 6' pairs of pins.
    Figures 7 and 8 illustrate a standard RJ-45 male connector. When plugging in such a connector into the female connector (Figures 5 and 6) according to the invention, the first 1 and second 2 pairs of pins are not connected to corresponding pins of the male connector. There are however wires 14 to 17 which are connected to those pins 1 and 2. The electrical connections 18 guarantee the transmission of signals from the corresponding wires 14'' to 17'' from the male connector (Figure 7) to the wires 14 to 17 from the female connector, since the signals are transmitted from the central 5 and further 6 pairs of pins to the first 1 and second 2 pairs of pins and follow the path 5''-5-1-14&15 and 6''-6-2-16&17.
    It should be noted that the central and further pairs of pins may be omitted from the male connector of Figures 3 and 4, or may be used according to an alternative for additional signals.
    Turning now to Figures 9 to 17, there is shown a second preferred embodiment of the contact set according to the invention. Same reference numerals have been given to same or similar features.
    The male connector according to Figure 9 comprises also the first 1', second 2', third 3' and fourth 4' pair of pins as described before. According to this embodiment, each pair of pins is provided in a corresponding holder part. Accordingly there are four holder parts, which are separated by a shield 20. Preferably the shield 20 is provided for grounding the further pair of pins 6 of the female connector (see Figure 15) upon connection of the male connector. This may for example be achieved by providing a connection plate 21 connecting the shield 20 with the pins 6. According to this embodiment, the central pair of pins 5 is also grounded. According to an alternative, the shield makes only contact with the further pair of pins so that the central pair of pins may be used for an additional electrical signal.
    The male (Figure 12) and female (Figure 17) connectors further comprise connection forks 22 provided for readily connecting the wires of the cable (not shown).
    As illustrated in Figure 14, the second connection pins 2 are separated into two portions 2a and 2b. Similarly, the first connection pins 1 are separated into two portions (not shown). The central pair of pins 5 is connected to a first electrical contact (not shown) connecting the central pair of pins with the first pair of pins 1. Similarly, each pin of the further pair of pins 6 is connected to a second electrical contact 26 connecting the further pair of pins 6 with the second portion 2b of the second pair of pins.
    Upon connection of the male connector according to Figure 11 into the female connector according to Figure 14, protrusion 23 provided on the male connector will release the contact between the second electrical contact 26 from the second portion 2b of the second connection pins and connect at the same time the first portion 2a with the second portion 2b from the second pair of pins so that electrical signals from the wires connected to the second pair of pins 2' of the male connector are transmitted to the corresponding wires connected to the second pair of pins 2 of the female connector. Similarly, protrusion 23 will release the contact between the first electrical contact (not shown) from the second portion of the first connection pins and connect at the same time the first portion with the second portion from the first pair of pins 1 so that electrical signals from the wires connected to the first pair of pins 1' of the male connector are transmitted to the corresponding wires connected to the first pair of pins 1 of the female connector.
    Preferably the male connector according to Figures 9 to 13 comprises a protuberance 24 and the female connector comprises corresponding notches 25 (as illustrated in Figure15), in order to prevent the connection of the male connector according to the invention in a conventional female RJ-45 connector. Connection of a conventional RJ-45 male connector to the female connector according to the invention is still enabled.
    Upon connection of a conventional RJ-45 male connector, the first electrical contact connecting the central pair of pins with the first pair of pins will be held, so that electrical signals from the wires connected to the central pair of pins of the conventional male connector are transmitted to the wires connected to the first pair of pins 1 of the female connector. Similarly, the second electrical contact 26 connecting the further pair of pins 6 with the second pair of pins 2b will be held, so that electrical signals from the wires connected to the central pair of pins of the conventional male connector are transmitted to the wires connected to the second pair of pins 2b of the female connector.
    Upon comparison of the two preferred embodiments, in particular Figures 6 and 15, it will be clear that the different pairs of pins in the female connector must not mandatory be provided in separate holder parts. In the male parts however (see Figures 4 and 10) separation between at least the first, second and other pairs pins must be provided. Preferably, a separation between the third and fourth pair of pins is achieved by providing a shield for grounding at least said further pair of pins.
    The description always referred to signals from the wires connected to the male connector to the wires of the female connector. It should be clear that signals may also be transmitted in the other direction.
